Emily,
Why don't you try your GP.
I totally understand your frustration, and desperation, and this will be being picked up along with everything else. Explain how you are feeling, (angry, frustrated, desperate, depressed?), and see if they can do anything to help the world stop seeming so bleak, without checking in to your local unit. Hopefully college is going ok, draw on that sense of achievement sweetie, it will get you through.
